Can you break > into a loader prompt with just the forth loader and tell me what "show > hint.acpi.0.rsdp" looks like? This doesn't appear to "just work out-of-the-box" yet when EFI booting amd64, as I still get the 'no local APIC' panic (I just tried @r329609). Under EFI and lua loader, the following is set when breaking to prompt: hint.acpi.0.disabled=3D1 Under forth loader, this is not present/set. In neither case is hint.acpi.0.rsdp present/set as that appears to get set during the exec of the loaded kernel... I've worked around the issue by adding hint.acpi.0.disabled=3D"0" to loader.conf (or patching the amd64 efi loader code to explicitly clear that hint). [Apologies for broken quoting, currently mobile] What happens if you patch this line out? https://svnweb.freebsd.org/base/head/stand/lua/core.lua?view=3Dmarkup#l233 I'll have to go back and figure out what I was thinking here again. It made sense when I wrote it, maybe explicitly disabling ACPI if it's not immediately detected was the wrong move. =3D)
